We have worked on improving the crash reports. When installing, please be sure to fill in the userinfo.txt file with your details. In the event of a crash it will help us get in contact with you to narrow down the problem further.

Should Uplink crash while playing, an ‘Error Report’ dialog box should come up, please do click on the ‘Send Report’ button. The crash report, together with userinfo.txt and debug log file will be sent to our server for further analysis.

At the moment we're focussing on the Windows platform. The bug fixes should be easily carried across to the Linux version. There are a few complications with carrying the fixes across to the Mac version, since we didn't do that port ourselves. We'll do our best though!
